Based on Pipo M9 Android stock release 20130506.
Fully rooted with Chinese bloatware removed.
Package includes Clockwork Mod Recovery and RKAndroid Tool to flash recovery. Also includes CWM TNT customized Android 4.2.2 installation and scripts to push CWM files and reboot to recovery.
Multi-user function has been activated, however, we expect this feature to function much better following an upcoming update.

"b" version changelog:
Includes all "a" improvements.
Multi-User now fixed. Installation includes Owner account plus Guest account. Guest account does not have root access.

*Note if you are installing on top of 20130422 firmware version, you will need to change the address (next to checkbox) where recovery is flashed to 00014000 from the default 00010000. If you reboot recovery to the dead android, you will need to reflash the recovery to the correct address.
**If you get an error while installing kernel image, do an advanced restore and flash system, data, and cache files. Wipe dalvik cache and switch back to RKAndroidTool. Use RKAndroidTool to flash the kernel only, which is found @ RKTools/Reboot Recovery/clockworkmod/backup/M9_4.2.2_TNT_V2_R2b/kernel.img.
***Any tablet that reboots to a blank screen instead of CWM is a V1 tablet. This CWM Recovery should work with V1 tablets for backup only!
****This version of Android 4.2.2 is NOT compatable with V1 tablets and may not become available for V1....Dansplans

The easiest install is on top of Android 4.2.2. The kernel flashing error only seems to occur when the builds contain different kernels. You can install this over any Android version, but may need to use advanced restore instructions.
